As a Software Engineer, I design both monolithic and microservice architectures and build APIs that connect web and mobile applications to the needs of businesses and organizations.
I build applications for public services and business operations, from API design and data management to web interfaces. I also develop mobile applications with Flutter. My Information Systems background helps me understand the people and workflows behind each product.
At the North Sumatra Provincial Communication and Informatics Office, I work on the backend of the SUMUT Cerdas Tourism Service, including catalog APIs, personal trip features, and nearby discovery. My work with WOKA and PTPN IV Regional I spans requirements analysis, web development, testing, and system maintenance.
Projects I developed with teams in corporate and public service environments.
Two internal applications supporting business workflows and access to company information.
A central platform to create, schedule, monitor, and find meeting recordings across multiple Zoom accounts.
Reduced the meeting setup workflow from 3–4 minutes to under 1 minute.
Built availability checks across accounts, centralized scheduling, recurring meetings, and a cloud recording dashboard.
A single portal for internal applications, official memos, and user administration.
Centralized access to work applications for Regional Management.
Developed the dashboard, memo and application management, and access permissions for admins and users.
The Tourism Service powering SUMUT Cerdas web and mobile applications.
I designed and developed the Tourism Service with Laravel as one of the microservices in the SUMUT Cerdas Superapp. It provides tourism data and trip planning features to web and mobile applications.
Visit SUMUT CerdasPublic APIs cover destinations, cultural heritage, event calendars, public transport, accommodation, and dining across North Sumatra, with search, filters, and pagination. Content management endpoints are restricted to admins through JWT authentication.
Nearby search combines locations across categories and sorts them by distance. It uses a Redis Geospatial Index and falls back to database distance calculations when the index is unavailable or out of sync.
Authenticated endpoints support personal bookmarks and itineraries linked to user identities from SSO.

Experience across backend development, web applications, and IT support informs how I solve problems throughout the development process.
